National Beat Up Vinny Day is the day on the 27th of November where you can beat up anyone named Vinny and if they fight back you are allowed to hit them with a semi-truck.
Oh hey, it's NationalBeat Up Vinny Day, you know what that means, Vinny!
A person you hate intensely not because they deserve such hatred but because they serve as a focus for your general hatred. A healthy way to dispense with excess animosity.
Jake's not really that big an asshole. He just serves as my hate sink.
